Besides using 2 /\*@pjs \*/ directive comment blocks, those image filenames don’t match the 1s you’ve uploaded there! 😱

They even lack the file extension “.png”! Capitalization fails to match either! 😵

For example, the 1st image you request in /\*@pjs \*/ is “imgHeart1”.  
However, the uploaded filename is just: “heart1.png”. 🙄
